I would stock freshwater prawn seed in farm ponds, alone or together with carp, feed and manage water quality, and harvest prawns for local markets, restaurants and traders.
Freshwater prawns fetch good prices compared with common fish and suit inland farmers with ponds.

Many farmers have ponds used only for carp or for water storage. Freshwater prawns can be grown in the same ponds and fetch much better prices than common fish. I would add prawns to pond farming, managing water and feed carefully, and sell to restaurants and local markets that pay well for fresh prawns.

Prawns are in strong demand in Indian cities and restaurants, and most supply comes from coastal brackish water farms. Inland farmers can grow freshwater prawns and serve nearby towns with fresh stock. Farm ponds built for irrigation and fish culture already exist in many states. Seed from hatcheries is available in several regions.
Buyers are restaurants, hotels, local fish markets, traders and households. Their trigger is demand for fresh prawns at good prices. I would reach them by visiting restaurants and fish markets with samples near harvest time.
I sell harvested prawns by weight, graded by size, to restaurants, hotels, fish markets and traders. Larger prawns fetch noticeably higher prices, so grading matters. Selling live or very fresh prawns directly to restaurants in nearby towns usually pays more than selling to a trader at the pond side. Carp grown in the same pond add a second income at harvest. Costs are seed, feed, pond preparation, aeration electricity, water testing, labour and harvesting.
The edge is fresh, inland supply. Restaurants in inland towns usually get prawns that have travelled far on ice, so fresh local prawns are noticeably better and easy to sell.
I would recommend this to a farmer with a pond and patience to learn. I would avoid it without training. Start with a mixed carp and prawn pond.

On an existing farm pond, the main costs are pond cleaning and preparation, liming and water conditioning, prawn seed from a reliable hatchery, feed, an aerator, water testing kits, nets and harvesting equipment. Depending on pond size and stocking, the total runs from tens of thousands to lakhs per cycle. Feed and seed are the largest costs.
Income depends on survival rate, growth to good sizes and market prices at harvest time. Prawns are more sensitive to water quality than carp, so management decides results. Growing them alongside carp spreads risk, because even a weak prawn harvest still leaves fish income. Direct restaurant sales and partial harvests of larger prawns help improve returns.
No sourced cost or earnings figures exist for this idea yet, so none are shown. Nothing here is an estimate.
